Days
On the night of August 8th, thousands of people around the world switch off their lights to push back against light pollution — and see the stars the way they were meant to be seen.
Light pollution washes out our night skies, wastes energy, disrupts wildlife, and affects our sleep. 8.8 is one shared night a year when we do something about it — together. Switch off between midnight and morning, step outside, and rediscover what the night really looks like.
The 8.8 app is your companion for the campaign — before, during, and after the night of August 8th.
Sign up for this year's 8.8 and choose how you're taking part — as a home, a business, a restaurant, or a whole community.
Pledge simple actions like turning off your lights on the night of August 8th, and get reminders when the moment arrives.
Post what you did and the sky you saw to the public stream, and explore moments shared by participants everywhere.

Between campaigns, 8.8 keeps you connected to the sky above you.
